Simply use the formula they give you. For question 6, 4 is the radius. So the area of the circle is 4pi. Now for seven you do the same thing, but they gave you the diameter instead and it’s a half circle. So try that one on your own. Let me know if you get stuck

Answer:
The difference between their volumes is 
Step-by-step explanation:
The attachment completes the question.
For cube 1:
For cube 2:
Required
The difference in their volumes
First, we calculate the volume of box 1
Substitute 8 for s1
Next, we calculate the volume of box 2
Substitute 6.5 for s2
The difference is then calculated as:
Hence, the difference between their volumes is
P = ( 2 / 3 )s;
s = ( 3 / 5 )t ;
p + s + t = 280 ;
Then, p =( 2 / 3 )( 3 / 5 )t ;
p = ( 2 / 5 )t;
We solve the equation : ( 2 / 5 )t + ( 3 / 5 )t + t = 280 ;
( 2 / 5 )t + ( 3 / 5 )t + ( 5 / 5 )t = ( 1400 / 5 )t;
10t = 1400 ;
t = 1400 ÷ 10 ;
t = 140 postcards has Tim;
p = ( 2 / 5 ) × 140 = 56 postcards has Paul;
s = ( 3 / 5 ) × 140 = 84 postcards has Shawn ;
You would make X amount of dollars. I can’t give you an exact amount of money because you didn’t tell me how much you make per hour!
